For coordinates combined in a single column, the most common formats are well supported, such as `"-123.3596, 48.4268"`, `"-123.3596; 48.4268"` or even `"POINT(-123.3596 48.4268)"`.

In addition, the data source needs to implement the [Table](https://hexdocs.pm/table/Table.html) protocol.
To put the data as a source on the map, use the `add_table_source/4` function by giving the data as the third argument and a tuple with the coordinates information as the fourth. Geometry properties are supported through the function `add_table_source/5`. Just pass the list of columns you want to add as properties as the last argument.
